Individual tensiometer for measuring tension in a string

摘要

An individual tension meter (1) for measuring tension in a racquet string (9), includes a graspable body (10) and a stress member (2) for stressing the string (9) that are movable relative to each other by pivoting, elastically deformable return elements (3) configured to urge the graspable body (10) and the stress member (2) relative to each other back into a neutral angular position, measurement elements for measuring a magnitude representative of the relative pivoting between the graspable body (10) and the stress member (2), and computation elements for computing the tension of the string as a function of the measured magnitude. The graspable body (10) and the stress member (2) have a first possibility of pivoting relative to each other in a first direction and a second possibility of pivoting relative to each other in a second direction opposite from the first direction.

1. An individual tension meter for measuring tension in a racquet string, said tension meter comprising:
a graspable body to be taken hold of in a hand; a stress member configured to stress the string by deforming said string, said stress member including at least two bearing elements spaced apart from each other, the at least two bearing elements being one or more of studs, fingers and prongs, the at least two bearing elements being positionable on either side of the individual string, said graspable body and said stress member being movable relative to each other substantially in a pivotal relative movement; elastically deformable return means connected to the graspable body and to the stress member for stressing the string, and configured to urge the graspable body and the stress member relative to each other back into a given angular position, the given angular position being a neutral position; measurement means for measuring a magnitude representative of the relative pivoting between the graspable body and the stress member; computation means for computing the tension of the string as a function of said measured magnitude; and activation and deactivation means for activating and deactivating said computation means as a function of the angle of relative pivoting between the graspable body and the stress member, wherein the graspable body and the stress member have two possibilities of pivoting relative to each other and relative to said neutral position, the two pivoting possibilities including a first possibility of pivoting in a first direction adapted to a right-hander, and a second possibility of pivoting in a second direction adapted to a left-hander, opposite from the first direction, and the computation means are formed by an electronic and computer system, the electronic and computer system being a microprocessor, the computation means being configured to compute the tension of said string both when the stress member and the graspable body are pivoted relative to each other in the first direction, and when the stress member and the graspable body are pivoted relative to each other in said second direction.
